Phenotypic screening of existing drugs is a good strategy to discover new drugs. Herein, 33 psychotherapeutic drugs in our drug library were screened by phenotypic screening and penfluridol (PFD) was found to exhibit excellent anti-endometrial cancer (EC) activity both and . Furthermore, the molecular target of PFD was identified as septin7, a tumor suppressor in EC.

Addition of pembrolizumab to neoadjuvant chemotherapy followed by adjuvant pembrolizumab improved outcomes in patients with high-risk, early-stage, triple-negative breast cancer. However, whether the addition of neoadjuvant pembrolizumab to chemotherapy would improve outcomes in high-risk, early-stage, estrogen receptor-positive/human epidermal growth factor receptor 2-negative (ER/HER2) breast cancer remains unclear. We conducted a double-blind, placebo-controlled phase 3 study (KEYNOTE-756) in which patients with previously untreated ER/HER2 grade 3 high-risk invasive breast cancer (T1c-2 (≥2 cm), cN1-2 or T3-4, cN0-2) were randomly assigned (1:1) to neoadjuvant pembrolizumab 200 mg or placebo Q3W given with paclitaxel QW for 12 weeks, followed by four cycles of doxorubicin or epirubicin plus cyclophosphamide Q2W or Q3W.

Background: The association between systolic blood pressure and all-cause mortality differs between frail and nonfrail individuals, highlighting uncertainties about the effectiveness of antihypertensive treatments in frail populations.

Methods: Using data from the SHEP trial (Systolic Hypertension in the Elderly Program), a baseline frailty index (FI), including 55 variables, was constructed. Fine-Gray subdistribution hazard models and Cox proportional hazards regression models were used to explore the association between baseline FI and the risks of stroke, cardiovascular disease, and all-cause death, as well as to examine whether the impact of antihypertensive treatment on these outcomes was modified by baseline FI.

Background: We performed a prespecified subgroup analysis of the CATIS-2 trial (China Antihypertensive Trial in Acute Ischemic Stroke II) to compare the effect of early versus delayed antihypertensive treatment on death and disability in patients with and without medical history of hypertension.

Methods: CATIS-2 is a multicenter randomized clinical trial conducted in 106 hospitals in China. The trial randomized 4810 patients with acute ischemic stroke within 24 to 48 hours of symptom onset and elevated systolic blood pressure between 140 and <220 mm Hg to receive antihypertensive treatment immediately after randomization or to discontinue antihypertensive medications for 7 days and then receive treatment on day 8.

Short-chain chlorinated paraffins (SCCPs) are a persistent organic pollutant, and limited information is available on their bioaccumulation and trophic transfer, which would be affected by carbon chain length, chlorine content, and hydrophobicity. In this study, relevant data on SCCPs in water, sediments, and organisms collected from Laizhou Bay were analyzed to investigate the specific distribution of SCCPs and their bioaccumulation and trophic transfer. In water and sediments, the average SCCP concentrations (ΣSCCPs) were 362.

Purpose: To evaluate the consistency and agreement between portal venous pressure measured by fine-needle (F), portal vein catheterization (D), and hepatic vein balloon-occlusion (W) in decompensated cirrhotic patients with intrahepatic venovenous shunts (IHVS).

Materials And Methods: 156 consecutive patients planning to receive transjugular intrahepatic portosystemic shunt in our center were screened for study participation. The F/D/W were assessed for consistency by Pearson coefficient (r), linear regression coefficient (R), and intraclass correlation coefficient (ICC), and for disagreement (error exceeding 20% of D) by Bland-Altman method.

Background: Currently, validated biomarkers for assessing hemorrhagic transformation (HT) after intravenous thrombolysis (IVT) are lacking. We aimed to validate a test combining GFAP (glial fibrillary acidic protein) and UCH-L1 (ubiquitin C-terminal hydrolase-L1) to indicate the absence of HT after IVT.

Methods: We prospectively enrolled consecutive patients with stroke treated with IVT from 16 hospitals.

CT is crucial for diagnosing chest diseases, with image quality affected by spatial resolution. Thick-slice CT remains prevalent in practice due to cost considerations, yet its coarse spatial resolution may hinder accurate diagnoses. Our multicenter study develops a deep learning synthetic model with Convolutional-Transformer hybrid encoder-decoder architecture for generating thin-slice CT from thick-slice CT on a single center (1576 participants) and access the synthetic CT on three cross-regional centers (1228 participants).

Article Synopsis
  • Macrophages are diverse cells that inhabit all body tissues, with specific types residing in organs and additional subtypes recruited during injury.
  • A specific population of recruited macrophages, marked by certain gene expressions, has been linked to fibrosis in various injury and cancer models.
  • Blocking Notch2 increases these macrophages in the lungs, but evidence suggests they actually help reduce fibrosis rather than cause it, highlighting their potential protective role during lung injuries.

In order to investigate the influence of the CaO and fly ash (FA) dosage and proportion on the mechanical properties, durability, and microstructure of solidified sludge, freeze-thaw (F-T) cycles and dry-wet (D-W) cycles are conducted to study the change in appearance and the strength attenuation of CaO-FA solidified sludge. Low-field nuclear magnetic resonance (LF-NMR) is used to analyze the microstructure of the solidified sludge with various dosages and ratios of CaO-FA. The results demonstrate that the unconfined compressive strength (UCS) and direct shear strength of solidified sludge increase with the prolongation of the curing age.

  • Advanced urothelial cancer displays significant genetic diversity and involves complex interactions between internal and external mutagens, which contributes to its deadly nature.
  • The study revealed that APOBEC3-induced mutations occur early during tumor development, while chemotherapy leads to a surge of later mutations, with both processes affecting the structure of extrachromosomal DNA.
  • Findings emphasized the role of circular ecDNA in the development of treatment resistance, specifically through CCND1 amplifications, highlighting key mechanisms that can inform future cancer therapies.

Despite therapeutic efficacy observed with immune checkpoint blockade in advanced melanoma, many tumors do not respond to treatment, representing a need for new therapies. Here, we have generated chimeric antigen receptor (CAR) T cells targeting TYRP1, a melanoma differentiation antigen expressed on the surface of melanomas, including rare acral and uveal melanomas. TYRP1-targeted CAR T cells demonstrate antigen-specific activation and cytotoxic activity and against human melanomas independent of the MHC alleles and expression.

  • Microplastics (MPs) contamination in marine environments poses ecological risks, particularly in the East China Sea (ECS), due to their interaction with other pollutants and harmful additives.
  • A study found high abundance of MPs in both bottom water and sediment, primarily made up of polyester, polyethylene, and polypropylene, indicating strong correlations between MP presence and levels of heavy metals and halogenated flame retardants.
  • The research suggests that MPs can act as carriers for pollutants, enabling their transport and co-settlement in marine environments, which highlights the need for better management and control of MP contamination.

Background: Although primary hyperparathyroidism (PHPT) is readily diagnosed biochemically and can be cured with low-risk surgery, it is often underrecognized and undertreated. Our objectives were to characterize, within our health system, how often patients with hypercalcemia were evaluated for PHPT and how often patients with PHPT underwent definitive treatment with parathyroidectomy.

Methods: Ambulatory patients aged 18 years or older seen at our health system between January 2018 and June 2023 with chronic hypercalcemia were identified from the medical record.
